[Buildroot] [PATCH] package/qt5tools: enable build of host qdoc

[yann.morin at orange.com]

From: "Yann E. MORIN" <yann.morin at orange.com>

qdoc was previously built as part of qtbase (in the pre-5.6 era), but
with qt-5.6 it is now part of qttools.

With qt-5.12, it needs libclang to build, so be it...
